0.014” Flat Memory Nitinol Tip PTCA Navigation Wire with 24.8cm MCOAT Durable Lubrication

Product Overview

The Runthrough NS Floppy Guidewire designed as universal baseline workhorse for daily diagnostic and interventional cardiac catheterization, the DuoCore floppy model balances pushability, trackability and tactile feedback to simplify routine preoperative wire selection. The seamless metal transition eliminates torque attenuation during long-distance vessel tracking, while flat memory nitinol distal segment maintains customized tip geometry after repeated lesion crossing. Exclusive MCOAT coating forms firm adhesive lubrication film that resists peeling after multiple serial stenosis passes; the reserved 2mm uncoated silicone tip retains clear hand feel to prevent blind subintimal entry. A continuous 3cm platinum-nickel radiopaque spring coil is integrated at the distal working zone for full lesion boundary positioning under standard fluoroscopy. This device is optimized for mild uncomplicated coronary lesions only; heavy calcified plaques and full chronic total occlusions require high-penetration dedicated guidewires instead.

Key Highlights

• Proprietary DuoCore Seamless Weld Dual-Shaft Architecture: Proximal stainless steel provides steady rail support, flat memory nitinol distal enhances shaping retention & anti-kink performance.
• Full MCOAT Abrasion-Resistant Hydrophilic Sleeve: Optimized coating substrate bonding ensures long-lasting slippage during multi-segment stenosis navigation.
• 2mm Uncoated Silicone Tactile Distal Tip: Reserved hydrophobic zone delivers clear operator feedback to reduce false lumen accidental entry risk. 
• Lossless 1:1 Synchronous Torque Transfer: Seamless metal joint eliminates torsion lag inside mildly tortuous coronary branches.
• 3cm Continuous Integrated Platinum-Nickel Radiopaque Coil: Uninterrupted marker segment achieves complete lesion visualization without fluoroscopic blind spots.

Technical Specifications & Construction

Two factory tip options: manually reshapable straight tip / factory pre-formed mild J tip; distal full MCOAT hydrophilic coating, terminal 2mm silicone uncoated tactile zone; 3cm continuous platinum-nickel radiopaque coil fixed at distal working segment, proximal shaft covered wear-resistant PTFE outer jacket.

Typical Clinical Applications

General baseline navigation wire for routine diagnostic angiography & mild-complex PCI in general cardiac cath labs, applicable to five core mild lesion scenarios:

• Elective Single & Multi-Vessel Non-Calcified Routine Coronary PCI
• Drug-Eluting Stent & Compliant Balloon Stable Delivery Operations
• Mildly Tortuous Vessel & Simple True Bifurcation Lesion Crossing
• Initial Wire Access for Medium-Length Non-Calcified Serial Stenosis
• First-Choice Guidewire for Routine Diagnostic Coronary Angiography

Quality Assurance & Compliance

All DuoCore floppy baseline guidewires are manufactured in Class 100 ultra-clean production facilities under full ISO13485 QMS control. Each batch executes exclusive dual-core seamless weld torsion fatigue test, MCOAT coating adhesion stability inspection and flat nitinol tip shaping retention testing. Every finished wire undergoes one-by-one coating smoothness and radiopacity inspection before packaging.
